Hello!
<u><em>Answer:</em></u>
<u><em>n=-9</em></u>
<u><em>*The answer must have a negative sign.*</em></u>
Step-by-step explanation:
First, you subtract by 7 from both sides of an equation.

Then, you simplify.

Next, you divide by 2 from both sides of an equation.

And finally, simplify and solve. You can also dividing into the groups.


Hope this helps!

2x+7x= 180
9x=180
x=20
Plug the x value in to both expressions
2(20)=40
7(20)=140
Final answer: 40 degrees, 140 degrees
Answer: A?
Step-by-step explanation:
Depending on how it is written, it could be either of these following solutions:
f(x) = x/2 - 6 or f(x) = x/(2-6)
For the first, we solve for x by replacing f(x) with 0
x/2 - 6 = 0
x/2 = 6
x = 3
For the second, do the same
x/(2-6) = 0
x/-4 = 0
x = 0
